supported b the pump tubing, the bearing including a sorbent antifriction ringslubricated by moisture from Water passing through the pump tubing, and means for so confining the antifriction rings as to prevent.

the dow oi water between them and the pump shaft.

Figure l is a vertical section through fragments of adjoining pump tubing sections, the connections therefor, and my bearing. Fig. II is an inverted plan view of my bearing. Fig. III is a perspective'vievv of one of the segments of `the wooden antifriction rings of mv bearing. Fig. IV is a perspective View of one of the leather antiiriction rings.

in the drawings: A and A designate pump tubing sections joined byflange rings' B and E', as is usual in the building up of pump tubing. f

1 designates the top member of my shaft bearing `vvhich is set into the fiange rings B and B', the said top member having a transverse 'web Q, and ports 3, through which Water may pass when 'forced upwardly in the pump tubing. The top member l supports sleeve d containing a vertical cavity 5, providing an annular space around the pump shaft, the cavity being open at its upper end and terminating in a base shoulder 6. The sleeve 4 terminates at its lower end in a conical' extension 7, with the object in view or lessening retardation of the upward 'dow of `Water to and through lthe ports 3;

. and, with a similar object in vievv, i provide V-shaped tins 8, which extend downwardly along the sleeve 4, beneath the web 2 of the `top member l or my bearing.-

9 and 10 designate, respectively, Wood and leather antiiriction rings located in the cavity 5 of my bearing. These rings being ar ranged alternately so that a leather ring is interposed between tvvo adjacent Wooden rings, or vice versa, Within the cavity, with the shaft C in contact With all of the rings. The .lowermost antifriction ring rests upon the base shoulder 6 at the bottom of the cavity 5, and all of the rings are conined in said cavity by a gland 11 having a lower extension 12, Which is seated in the cavity and bears on the topmost antifriction ring. The gland 11 is held against the antifriction rings by suitable means providing for its adjustment, such, for instance, as screw threaded stems 13 attached to the top member 1 of the bearing, the stems being extended through the gland and being provided with nuts 14,

through the medium of which any desired adjustment of the gland may be obtained. The Wood rings 9 are preferably made of segments, as seen in Fig. HI, but the leather rings 10 may be of non-sectional form, as shown in Fig. IV, the object in making the wood rings of sectional form being to avoid their breakage in slipping them onto the pump shaft, it being obvious that the leather rings being flexible and yielding, there is no necessity of making them sectional.

From the foregoing, it will be understood that the anti'riction rings 9 and i@ are coniined by the gland extension 12 in the cavity 5 in such manner as to exclude Water passing through the pump tubing from iovvin into the cavity; but it is obvious that a sulcient supply of moisture may gain access to the cavity in vvhich the antifriction ringsl are located to keep them suciently moist for o lubrication, so that vvear upon the pump shaft or the antifriction rings will be reduced to a minimum. The Wood and leather antifriction rings are, therefore, kept in such condition as to rendei` them very durable.

it will be obvious that a screvv threaded connection or a connection of any other suitable form, for uniting lthe pump tubin sections might be utilized in lieu of the ange rings B and B; and that,.if the screvv threaded connection is used, the body of the bearing may be screwed into such connection. I claim 1. The combination with two sections or pump tubing and flange rings secured to means in said cavity, and aA gland adjustably interposed between the sleeve and. the lower secured to said top member and extending tubing section to centralize the bearing, the

into said cavity. y

2. The combination with two sections of pump tubing and ange rings secured' to top member and its sleeve being provided with a cavity, antifricton means in Said cavl ity, and a'gland adjustably secured to said-15 said sections and joined to each other, of a top member and extending into said cavity.

bearing comprising a, ported top member set into said flange rings, the said top member being formed with a downwardlv extending l0 sleeve `nd with downwardly extending ns JOSEPH H. GWATHMEY. In the presence of- R. C. HILLIARD, J. V. HEGWooD.
